.This invention relates to Hush tanlrfaucets used in conne'ctionivithsewer systems and more particularly to regulating attachments for said faucets.

In sewersystems, what are known as flush tanks are used, one at the end of eachsewer ous expedients have been employed to let` the Water run, but itpwasfound .that leither too much Water was Wasted or if ya hole in the curved attachment sufhciently small to permit the proper amount of Water to fioiv through was made, such a hole would Asoon be` come stopped up by sediment discharge point thereof. i

This .invention Was designed to overcome these difficulties, and the attachmentlconrstituting this invention operatesxon just the opposite principle of the oldmethod, thatis,

settling inthe the Water instead of flowing down is directed upwardly through the small opening to prevent all possibility of sedimentV settling around andclosing it. 1

Anotherobiect of the invention is to ,so construct an .attachment ofthis character which Will perfor-m' thedouble vpurpose of regulating-the constant flow of water and in case any obstruction/should get into the .deviceit will only be necessary tolm'an-ipulate .uit slightly to loosen anyV accumulation, giving the water an opportunity yto flush said accumulation out of the spout.

Still another object is to so construct an attachment for a faucet of this character which will discharge a continuous stream of desired size which may be regulated to any desired extent and completely shut off if desired to do so. s

Still another object is to provide adevice of this character which is simple, being yWhich may be easily applied an d adjusted to meet desired requirements. i

, In carrying-out'these objects the invention is susceptible of modification Without depart'- ing from the spirit or sacrificing any ofthe advantages-of ytheclaimed invention; there being shown in the drawings for illustrative purposes a preferred and practical form, in which;`

Figurey lrel'qrescnts aside elevation of a :i:

flush tank faucet equipped Withthe attachment constituting this invention, "Figa 2 is a transverse vertical section through the attachment,

Inthe embodiment illustrated,a iiushitank 1"" faucet l is shown havingL the usual hand valve v2, said faucet being .designed to be attached yto a Water line, not shown, usedin connection with a sewer fiush tank.' A three-Way T-coufr pling 3 is shown Withoneen'd' of Which the 7.

faucet' l is Connected andI .the other end of which is designed to be connectedbyasuitable union 4 With a Water line. The vshank 5 of this coupling 3 extends upwardly when theV device is inoperative position, and is externally threaded to receive al coupling/mit 6 Which unites the attachment l0 with `the T- couplingi, as is shown clearly Yin Fig.` 2. This .coupling nutG has an ineturned flange 7 at its outerend :which is designed` to overlie and 'clampingly Vengage alange 12'of the base llconstitluting a part of the attachment 10. A strainer 8 is located between the flange 12 'andthe' upper end of the shank 5 of the coupling 3 and is secured by tightening up of f2 the nut 6.1 This Astrainer operates to strain out any sediment in Vthe WaterV flowing throughI vthe coupling 8 and which is designed to p asfsfyout through fthe" attachment 10 in a Fig. 3 is a detail perspective view of the c manner presently to be described.

p The A,base 1 1 ofthe attachment 10 has'a reduced eXteriorly threaded tubular extension ,13 with Whi'chis designed to be engaged a tubular upper section 14,'the bore ofY which at its lower end, is enlarged toy fit thelextension im The valve stem. 1'5 is threaded throughout.

a portion of its length as shown at 16 and is designed to be screwed into the 'tubular membof 1.4 and with its,Unthreaded.portionto turn and slide freely in the extension` 13 of the base 11. T helower o r outer end 4of this stem 15 which is unthreaded as shown at 17 has eX- tendillg .longitudinally .thereof a grooveY 1 8 ihioh tapers .toward its inner 'end as' is shawn clearly: in AFig. 3, and is designedl foi` .Controlling the viator, and. permit it to nass from the hollow base 11 which 'is in communiooton with the ooupling 3 and the spout 14a throughl which the water'is discharged into the flush tank. It willl thus be seen that by adjusting thisvalve stem 15 by means ofthe finger grip 19 at the outer end thereof, the amount ofY water Passing, out through. the spout 14@ may bo Controlled .Sothataoontinuous stream may be supplied to the: tankand so regulatedthat the desired amount of Water will be supplied to the tank in the time des sired, causing the ,tank to dump ,automati- Acally in` a set timeaccording to the location o f the tank and the flushing ofthe sewer required. The tapered groov`e18 performs the double function-.0f regulating the Lconstant iiow ofjthe water andalso. provides means whereby any obstruction which might occur in the small opening of the attachment could be readily removed by turning-the stern 1,5 a few turns to .the left. to loosen theaccumu-la: tion, allowing, the, water to force it out through the spout. If necessary, of course, thevalve stem might be entirely'removedfor cleaningor other. purposes. Y The attachment 1.0 ism-ade. intwo sections -1-1 and 14, asabove` described, topermit `the base l11 to be unscrewedx fromgthe .upper section and allow the union or couplingV nut 6 which engages Vthe T-.coupling 3 to slip over the base and Vbe properly connected therewith. Y

fill-hisl attachment 10 fissubstituted for the old'form of.downwardlycurvedgspout attach ment now .inuse simply by unscrewing the nut Grwhichis used 'forl connectingthe curved attachment to the T-couplingshank, Vas well as this attachmenty 1Q. The nut. Gisthenreinovedfrom thecurved spout, and'applied to the attachment asv above described and .pei-.-

It will thus be seen that this attachment overcomes all the difficulties of the old method operating on the oppositey principle, that is, the water, instead of doing down, flows up through the small opening in the attachment, thereby preventing all possibility of sediment collecting around and closing up the passage. Y

vThis attachment has been thoroughly tested', and-proven absolutely successful.

g N Vithout vfurther description it is thought that the features and advantages of the invention will be. readily-'apparent to those skilled in the art, and it will of course be understood-thatchanges in the form, proportion and minor details of construction may beresorted to, without departing from thespirit and scope of the claimed invention.

I claim zl In a device of the classdescribed the combination with a flush'tank fau-Cet having a hand valve; of a tlireeway.T'-valve with one end of which said faucet lis connected, the other end ofisaid coupling having means for connection with a water line, .the shank of the coupling extending upwardlywhen in operative position, said shank being externally threaded to receive az coupling nut, a coupling nut engaged with said threaded shank portion and having an inturned flange at its outer end, a tubular member having an outturne'd iange at its lower endc adapted to underlie and engage with the flange of the nut, said tubular member having a reduced externally threaded section, a tubular upper section having an enlarged bore Lat its lower end to fit said tubular threadedV extension ofthe first mentioned eX- tension, the upper orouter portion of said bore being threaded to receive a valve stem, a downwardly and outwardly inclined spoilt carried by said upper sectionl and communieating with the interior of said tubular portion thereof, a valve stem threaded throughout a p'ortionof its length and having threaded engagement with said tubular upper section with its unthreaded'portion adapted to slide freely and turn in the reduced extension of the lower section, the unthreaded section of said valve stern havingn a groove extending longitudinally thereof vand tapering toward its inner` end for Vcontrolling the water. and permitting it, to flow fromthe hollow upper' section into thefiiush tank, the valve stem beingradjustable to vary 'the amount of1 water Y permitted to pass. i o
